well, the old pony is gone and the new one is here. i love it but it is so quiet compared to my 94gt. i regret to say that i am missing my old pony---any suggestions on what will help my 05roush sound better. it has the roush exhaust and so i was thinking an x pipe and maybe headers. i hate to say it but it feels kind of ricey or something. my previous car had flowmasters,catco hpipe w/cats and bbk headers and it sounded awesome! also, i was wondering if i went without cats would it kick a cel in the car? my 94 gt was very, very, very touchy about mods. i had to chip it with the new cam, idle probs and man she was just real bitchy about mods sometimes. im hoping the parameters of the newer mustangs are better.
